What kind of game is "Tetris"?

I had to quit Tetris after one day because I could see it when I closed my eyes and couldn’t sleep.

I have no clue what 2 of them mean. lol

i liked it but only when free cannot buy things.

RushMama2112, it's a puzzle in that the player is trying to fit the "pieces" together to form a line. A simulation type game is when the player is pretending to be something else, like a wolf or a bird. They go through the game doing things that animal would do in the real world.

Played and loved Tetris for more years than I'd like to admit. It als for mewas a "Gateway" game, as it introduced me to all kinds of gaming and before I knew it I was playing every type of game there is. I was gaming for hours everyday. I have it under control ( a little bit) now. But my favorite genres are TBsed RPGs, and also Action Adventure

Not a very well-worded question. Technically, it's a video game which is a kind of simulation.
